12 Circuit Bypass Module NMEA 2K without Fuse Pack & Jumper Wire

For manual control of the loads, an optional MPower® 12-Channel Bypass Module (CBMD12) can be installed in conjunction with the 12-Channel DC Load Controller Module (CLMD12). The maximum current capacity for the CBMD12 is 75 amps in 12V DC and 24V DC power systems.

The Bypass Module provides a manual method (ON/OFF switch) to control loads by providing power to each load in case of a CLMD12 malfunction or a NMEA 2000® network failure. The CBMD12 utilizes standard fuses for overcurrent protection and 12 Carling Curvette® Rocker Switches for manual control of each load. With the use of the Curvette rocker switches, there is no arcing that occurs while manually overriding a load. Furthermore, unlike other digital switching products, MPower does not require moving a fuse, which can cause electrical connections to degrade or the possibility of ignition.

It’s important to ensure that the current rating of the fuse for each load is appropriate to protect the load and the wiring for that load. Please note that the bypass module does not support paralleled outputs, since each circuit is controlled by a separate switch. Additionally, the bypass module does not support dimming of circuits.

Features:

  • 75 Amps maximum current capacity
  • Outputs
  • 12A Max (two outputs)
  • 10A Max (six outputs)
  • 5A Max (four outputs)
  • 12V and 24V DC power systems

Looks good but the wall anchors is TRASH!
Size: 3-tier shelves, Size: 3-tier shelves
The product is heavy and sturdy once you get it up completely. The issue I have is with the instructions... 1. The 5/16 drill bit is recommends is WAY TO BIG. The Anchors it comes with will slip right through. The screws that is comes with are WAY TO SMALL for the weight. I recommend getting better ones from the hardware store and painting the screws black for better aesthetics. 2. The instructions say to put it together first then hang it on the wall. That is great so you can see where you want to place it and because it is actually bigger than it looks, but you will need to de-assemble it from the bottom shelf down after you mark where you want to place it, then put that part on the wall, then reassemble it from there, securing the top part to the wall last. The instructions sucked but that is what worked best for me. Another thing is when you first assembling it, you will notice that you will have to unscrew it a bit so the pipes can fast the correct way. This will make it feel flimsy, but it will tighten up when you secure it to the wall. Also, like some people said in previous reviews, some of the black paint did peel off the pipes, not to much for me but it was noticeable if you look at it hard enough.

Love the look of these
Size: 24in-Shelve
I love the look of these. Bought for towel storage over my toilet. They look really classy and I'm so happy with them. However, its important to note that the wall anchors they provide are way too big for the screws. The screws just fall into the inside of the anchor without even being screwed in. So there's no way you could secure the wall unit with the ones provided. We had to replace the anchors with some I already had. Other than that very happy with the quality and look.

Great shelf
Size: 24in-Shelve
I’m a fan! Good quality, sturdy shelf, very easy to assemble and put on the wall. I recommend having a second person to help hold the shelf while you get the first few screws in, just to keep it level. I love the larger shelf space, it gives me a lot more storage for the bathroom.

Great Product!
Size: 3tiers-Shelves, Size: 3tiers-Shelves
This shelf system is an awesome option if you're looking for an industrial/rustic vibe. It's feels super well made and was easy to assemble. The finish on the wood is fantastic! All the hardware for mounting was there and even if you have minimal experience mounting brackets and hardware to the wall - this was still very easy. I especially appreciated the "U" brackets to secure the wood shelves to the posts - that was an unexpected extra that I was very happy to see included. Unfortunately because of space and the way my wife wanted these spaced, we didn't use the third shelf, but we're definitely going to find some place else in the house to mount that later. Overall, if you like this decor - I would definitely recommend this item!
